Insidious Director Jacob Chase to Helm New Blumhouse Horror Project Sleepover

Release date discrepancy: some outlets list Sleepover's release as Oct. 8, 2027 while others (including THR) report Oct. 8, 2028.
Insidious: Out of the Further opened to about $60.3 million worldwide on its opening weekend, contributing to the franchise reaching roughly $800 million worldwide at the box office.
Chase has described his approach to Out of the Further as treating it like the 'Citizen Kane' of the Insidious series, despite acknowledging it is the sixth installment.
Bryce McGuire of Night Swim is co-writing Sleepover with Chase; McGuire also serves as an executive producer, linking Sleepover to Night Swim's writer-director cohort.
Sleepover is a Blumhouse Atomic Monster production with Jason Blum producing; Lilly Tyson overseeing, and Cinescape Entertainment producing in conjunction with Blumhouse Atomic Monster.
Jacob Chase, director of Insidious: Out of the Further, is set to direct Sleepover for Blumhouse Atomic Monster and Universal Pictures. The horror film will arrive on October 8, 2027 or October 8, 2028 — sources differ on the exact year. Chase co-wrote the screenplay with Bryce McGuire, the filmmaker behind Night Swim, and the project marks another collaboration between Chase and Blumhouse Atomic Monster following his success with the Insidious franchise.
Sleepover is based on McGuire's original short story and promises to deliver what producers call "the quintessential sleepover nightmare." Jason Blum will produce through Blumhouse Atomic Monster, with Lilly Tyson overseeing the company's involvement. Cinescape Entertainment is producing alongside Blumhouse Atomic Monster, and the partnership underscores Universal's ongoing reliance on Blumhouse for horror content.
Insidious: Out of the Further opened to roughly $60.3 million worldwide in its opening weekend, according to reports. The franchise has now crossed approximately $800 million at the global box office. Chase has called his approach to Out of the Further like treating it as the "Citizen Kane" of the Insidious series, even though it is the sixth installment in the franchise.
The success of Out of the Further gives Chase momentum heading into Sleepover. His work on the Insidious sequel impressed both audiences and studio executives at Universal. The new horror project represents his third major feature for Blumhouse Atomic Monster, following Out of the Further and Come Play.
Bryce McGuire, who wrote and directed the underwater horror film Night Swim, co-wrote Sleepover with Chase. McGuire also serves as an executive producer on the project. This pairing links Sleepover to Night Swim's creative team and reinforces Blumhouse Atomic Monster's focus on hiring proven horror filmmakers.
McGuire created Sleepover's original short story, meaning the screenplay adapts his own material. Having the writer-director also serve as executive producer gives McGuire significant creative influence over the final film. The arrangement mirrors how many horror franchises maintain creative consistency across multiple projects.
Sleepover is the latest example of Universal's deepening partnership with Blumhouse Atomic Monster. The label has become the studio's go-to producer for horror films with franchise potential. Lilly Tyson oversees Blumhouse Atomic Monster's day-to-day operations, while Jason Blum remains the driving force behind the company's output and strategy.
The October 2027 or 2028 release date — sources conflict on which year — positions Sleepover as a major horror event for Universal. Cinescape Entertainment's involvement suggests the studio is confident enough to bring in additional production partners. This collaborative model has worked well for Blumhouse Atomic Monster on previous Universal releases.
